According to Jefferson Lab, an average 70 Kg person, that's

about 150 lbs, will have approximately 7*10 to the 27th atoms in

their body. That's 7 followed by 27 zeros


The number of stars in the Universe, which is estimated at 10*10

to the 21, or 10 followed by 21 zeros.


So you can see that there are way more atoms in your body than

there are stars in the universe.
